Brock Purdy’s Siblings: All About the San Francisco 49ers Quarterback's Sister Whittney and Brother Chubba

NEED TO KNOW

• Brock Purdy has an older sister, Whittney, and a younger brother, Chubba
• Both of the quarterback's siblings are also athletes, and Chubba plays for the University of Nevada
• Chubba has said that Brock has taught him a "ton in life and football"

Brock Purdy isn't the only athlete in this family.

The San Francisco 49ers quarterback grew up with his older sister, Whittney, and younger brother, Chubba, in Gilbert, Ariz. Their parents, Shawn and Carrie, took advantage of the city's advanced training facilities and brought up a trio of all-star athletes.

Whittney, the oldest of the three siblings, went on to play collegiate softball, while Chubba, the youngest, signed to play football at the University of Nevada. Meanwhile, Brock belongs to an elite team of his own — at least for the time being, until Chubba can join him in the big leagues.

Despite being the last pick of the 2022 NFL draft, Brock has carved out a name for himself as a quarterback for the 49ers. In December 2022, Brock led his team to victory against legend Tom Brady during his first NFL start, with his siblings and family present.

Thanks to the NFL, Brock and his siblings have been able to make even more memories in the last year. However, one of Brock’s favorites would have to be the time he pranked his family on draft day. After six rounds of not hearing his name called, Brock’s chances of getting drafted were slim. Then the 49ers general manager called.

“I come walking out to the living room and everyone is waiting,” Brock recalled to NBC Sports in September 2023. “It’s another free agency call,” he told his family, tricking them into believing that he didn’t get picked. “They’re like ‘no way, you’re lying,’ and I said, ‘that’s it.’ ”

“I’m trying to act all sad in the chair,” Brock laughed. Before the announcer read his name aloud, it appeared in big letters on the TV — leading to quite the reaction from the Purdys. “They all screamed and jumped up like I was a first-round pick,” he recalled.

Here’s everything to know about Brock Purdy's siblings, Whittney and Chubba, and their special bond with the quarterback.

Brock, Whittney and Chubba grew up in Arizona

Settling down in Arizona was a no-brainer for Shawn and Carrie, who grew up on opposite coasts. “He wasn’t going to California, and I wasn’t going to Florida. This was our compromise. And we love it," Carrie explained of their decision in a November 2019 piece for The Athletic.

The pair raised their children in Gilbert, about 25 miles southeast of Phoenix. The area was already somewhat familiar to Shawn, who had played minor league baseball in Arizona. As time went on and the Purdy kids got involved with sports, it quickly became obvious that Gilbert had been the right choice.

"The sports in Arizona were pretty good," Brock said in a December 2023 interview with the 49ers, leading up to a game at State Farm Stadium. "Just in terms of the competitive nature. I feel like I was a really good athlete because of the kids that I was around who loved playing sports."

Similar to Brock, Whittney and Chubba were also able to take advantage of year-round training thanks to Phoenix’s relatively placid climate.

Brock and Chubba have always had a competitive relationship

“Ever since we were little, competition has been everything,” Chubba told The Arizona Republic in August 2019. “We just always want to win and we don’t like losing.”

Chubba recalled one family vacation when he and his big brother came up with tricky challenges to see who could outthrow the other and whose skills were sharper and more precise. Whatever it was, Shawn said you could always count on “the gloves [coming] off when those two are together.”

Chubba got his nickname from his dad

Preston Purdy, who affectionately goes by “Chubba” around friends and family, earned his unique nickname when he was just 1 year old. In an interview with The Arizona Republic, Shawn recalled Preston being a “huge” baby, weighing 32 pounds ahead of his first birthday. And so, he began calling his youngest Chubba, as did the rest of their family.

The nickname stuck and has become Chubba’s professional name on the gridiron as well. The rising athlete said that he plans to legally change his first name to “Chubba” in the near future.

"Everyone calls me Chubba," he told the outlet. "People have said stuff like, 'Chubby,' but I don't care, because Chubba is my name.”

Whittney played collegiate softball

The next generation of Purdy athletes first started with Whittney. The oldest of her siblings, Whittney played softball at Spartanburg Methodist in South Carolina for two years, before transferring to Southeastern University, where she finished out her college career, alternating between third base and shortstop.

Simultaneously, Brock was trying to get ahead in football. But as he told The Athletic in July 2023, his arm was no match against his older sister’s, who “could launch it.” Nevertheless, Brock said Whittney was too kind and mature to ever hold it over him.

Chubba plays football at the University of Nevada

After initially announcing that he committed to play football next year at San Jose State University, Chubba said in a since-deleted post on X that he was going to the University of Nevada instead.

Chubba entered the NCAA transfer portal following a successful run at the University of Nebraska, where he made 12 game appearances. Prior to that, Chubba played at Florida State University from 2020 to 2021.

Whittney has a close relationship with Brock’s wife

In July 2023, Whittney announced on Instagram that she would finally be gaining a sister. Whittney, Chubba and the rest of their family were present when Brock got down on one knee and asked his then-girlfriend, Jenna Brandt, to marry him.

Whittney celebrated the milestone on Instagram, sharing a carousel of images from the special day and welcoming Jenna into their family.

“Such a great week celebrating Brock and Jenna🤍,” she wrote. “So excited to be gaining the most sweetest sister in law! Love you both & Cheers to an amazing year ahead🥂💍.”

Along with a few others, Whittney and Jenna took a trip to Telluride, Colo., for Jenna’s bachelorette party. “Had the best time celebrating my soon to be sister in law!!! Love you lots JB & cant wait to have you be part of the family soon!” she captioned an Instagram post from the trip.

Both of the Purdy siblings were there when Brock and Jenna tied the knot in April 2024. "They went to the chapel & they got married!!!!💒" Whittney captioned an Instagram post. "Congratulations to Mr. and Mrs.Purdy! It was so much fun celebrating you both! Love ya’ll so much🤍"

Jenn and Brock welcomed their first child, Millie Joleen, in July 2025.

Chubba credits Brock for being a big influence on his football career

During a March 2022 interview with the Omaha World-Herald, Chubba took a moment to sing his big brother’s praises. The younger Purdy acknowledged that Brock not only gave him his affinity for colder weather, but has helped teach him the ins and outs of football.

“My brother has helped me a ton in life and football,” Chubba told reporters. Amongst the many helpful skills Chubba’s learned from Brock, “reading defenses” and “teaching me the game” are at the top, he said.

“I really appreciate that from him. He’s had a ton of experience as well, he’s just taught me so much,” Chubba added.
